Lower Eyelid Blepharoplasty: Minimizing Complications and Correction of Lower Eyelid Malposition.

Lid retraction is a feared complication of lower blepharoplasty. Anatomical variations like negative orbital vector, horizontal lid laxity, and preexisting lid retraction are more prone to lid malpositions. Meticulous and precise execution of a series of surgical steps is key to preventing complications. This includes minimizing surgical trauma, meticulous hemostasis, preserving innervation to the medial lid and pretarsal orbicularis, safe method of fat excision, septal tightening while maintaining lid traction, and conservative and titrated skin excision. Canthal fixation addresses lid laxity and maintains the lid stretched vertically while postoperative healing and fibrosis are taking place. Post-blepharoplasty lid retraction may occur due to failure to address lid laxity and the occurrence of middle lamellar fibrosis. Excessive skin excision may also result in anterior lamellar deficiency. The "sag and drag" concept is useful to evaluate the post-blepharoplasty retracted lid. The treatment of the retracted lid includes lid massage, replacing the anterior lamella, or releasing the middle lamellar fibrosis or a combination of techniques. In conclusion, understanding the mechanisms of lid retraction, careful preoperative assessment, and surgical precision will help surgeons to prevent and manage this complication.

Lower Eyelid Transcutaneous Blepharoplasty, Minimizing Complications and Correction of Lower Eyelid Malposition.

The periocular area is one of the first and most noticeable areas affected by ageing. Common signs of lower lid ageing include rhytids, prominent eye bags caused by prolapse of orbital fat pads, increased lid laxity leading to lid malpositioning, and deepening of tear troughs, all of which give a sunken aged appearance. Lower lid transcutaneous blepharoplasty can correct most of these problems providing excellent long-term aesthetic outcomes with minimal downtime for the patient. However, lower eyelid anatomy is complex, and a thorough understanding of its structure and function is needed to avoid serious complications such as lid malpositioning and blindness. In this review, we present the anatomy of the lower lid and useful surgical techniques to circumvent and avoid such complications.

Gore-tex a magic sheet for symblepharon prevention!

Background: Symblepharon occurs as chronic sequelae of severe chemical injuries. The risk of recurrence is high due to unpredictable wound healing of conjunctiva and tenons following excision in young patients. Gore-tex aids in prevention of the recurrence of pterygium 1. Purpose: To present a surgical video on role of Gore-tex in grade 4 Symblepharon lysis. Synopsis: A 28-year-old male with a previous history of Grade 4 chemical injury presented with symblepharon and total obliteration of both upper and lower fornices after one year in the right eye. He underwent symblepharon lysis, Living related conjunctival allograft, Amniotic membrane graft and Gore-tex. The video explains the surgical steps in detail. A 360-degree complete peritomy was done, Symblepharon was released from the corneal surface, and the fibrotic tissue was extensively dissected away from the corneal surface and released into the fornix. Further, cryopreserved AMG was placed over the entire raw ocular surface and sutured to the episclera with glue. Prepared Gore-tex was placed on the superior and inferior fornix and sutured with 10-0 nylon suture. Again, AMG was placed over the Gore-tex in the fornices and covered with glue. A small 2x2mm biopsy of limbal stem cells from the superior limbus was already excised from the fellow eye (CLAG) and then Lr-CLAL was prepared from the patient's mother. These two grafts were placed on the nasal and temporal bulbar surface over the AMG and sutured to the underlying AMG and the episclera with glue. The entire surface was then covered with the AMG to promote epithelisation. At one month postoperative period, patient had stable ocular surface with intact Limbal conjunctival graft with mild conjunctival recurrence of fibrosis superiorly. Highlights: The video clearly explains the surgical steps of Symblepharon and the benefits of using Gore-tex. Online Video Link: https://youtu.be/aFfq2x9QBwA.

The addition of a conjunctival flap to a posterior lamella auricular cartilage graft: A technique to avoid corneal complications.

PURPOSE: To present the benefits of the addition of a conjunctival flap when correcting lower eyelid retraction using an auricular cartilage graft. METHODS: An auricular cartilage graft was obtained either from the concha o the scaphoid fossa. When preparing the receiving bed, the conjunctival incision was made 2 mm below the inferior margin of the lower eyelid tarsus, therefore, a conjunctival flap arising from the inferior border of the tarsus was obtained. The cartilage graft was placed in the lower eyelid. The inferior border of the graft was sutured to the retractors and conjunctiva using absorbable sutures. The superior border was sutured to the inferior tarsus, so that de conjunctival flap covered the superior portion of the graft. RESULTS: Fourteen patients underwent the surgical technique. No corneal complications were observed in the early or late postoperative period. Donor site complications were not encountered. CONCLUSIONS: The confection of a conjunctival flap that lines the superior portion of an auricular cartilage graft in the lower eyelid provides protection against corneal postoperative complications until the graft is epithelized.

[Eyelid hygiene in preparing dry eye patients for cataract surgical treatment]. / Gigiena vek v podgotovke patsientov s sindromom «sukhogo glaza¼ k operativnomu lecheniyu katarakty.

PURPOSE: To evaluate the effectiveness of complex treatment, including eyelid hygiene, on the condition of ocular surface in dry eye patients before cataract surgery. MATERIAL AND METHODS: The study included 56 female age-related cataract patients (64±4.3 years old) with dry eye caused by Meibomian gland dysfunction (MGD). The main group patients (n=28) underwent eyelid hygiene therapy (2 times a day, 1 month) that involved Blefarogel cleansing, Blefarolotion, Blefarogel-1. The main and control (n=28) group patients performed (during the month): «fat-water¼ type nanoemulsion instillation (3 times a day); preservative free vitamin-A application (at night). Methods included dry eye symptoms assessment (OSDI scale); TBUT; Shirmer-1 test; lissamine green vital staining with xerosis indicator calculation (van Bijsterveld scale); "lid wipers" symptom evaluation; Norn compression test. Statistical evaluation included: mean and standard deviation calculation (M±s); significance of differences assessment (Mann-Whitney U-test; Wilcoxon's T-test). RESULTS: The main group patients (artificial tear, keratoprotection, eyelid hygiene) showed a statistically significant more pronounced decrease in OSDI (from 33.2±3.1 points to 15.2±1.8 points) and a significantly more pronounced increase in TBUT (from 4.8±0.5 s to 6.9±0.4 s) than in control group patients (artificial tear, keratoprotection; respectively, from 32.7±3.2 to 20.8±3.1 points and from 4.85±0.5 to 5.8±0.4 s; p<0.05). Apparently, this was associated with a significantly more pronounced relief of the MGD signs in main group patients (from 2.1±0.1 to 1.1±0.2 points; p<0.05) as a result of eyelid hygiene. In the control group, the dynamics of MGD severity (from 2.08±0.3 to 2.11±0.5 points) was statistically insignificant. CONCLUSION: Eyelid hygiene (based on Blefarogel cleansing, Blefarolotion, Blefarogel-1) increases the effectiveness of dry eye treatment in MGD patients, compared with isolated tear substitution and keratoprotection.

Effects of perioperative magnesium sulfate with controlled hypotension on intraoperative bleeding and postoperative ecchymosis and edema in open rhinoplasty.

PURPOSE: This randomized, double-blind study was planned to evaluate the effect of perioperative magnesium sulfate with controlled hypotension on intraoperative bleeding, postoperative ecchymosis and edema, and side-effects. MATERIALS AND METHOD: Forty-nine patients undergoing open rhinoplasty were divided into two groups - magnesium sulfate and control. The magnesium sulfate group received 30-50 mg·kg-1 intravenously as a bolus before induction of anesthesia, followed by 10-20 mg·kg-1 h-1 by continuous intravenous infusion during surgery. Anesthesia was induced with propofol 3 mg·kg-1, fentanyl 15 µg·kg-1 and cisatracurium 0.6 mg·kg-1. Mean arterial pressure was maintained at 50 to 60 mmHg under controlled hypotensive anesthesia with magnesium sulfate titration. Hemodynamic variables, operational bleeding, early postoperative side-effects and postoperative first-, third- and seventh-day ecchymosis and edema were compared between the groups. Ecchymosis and edema were evaluated using a graded scale from 0 to 4. RESULTS: In the magnesium sulfate group, mean arterial pressure decreased during most of the perioperative period. Intraoperative bleeding also decreased. A distinct reduction in ecchymosis and edema was observed in both the upper and lower eyelids on the first, third and seventh days. Patients in the magnesium sulfate group also had a more peaceful postoperative course with less postoperative nausea vomiting, and shivering. CONCLUSION: Magnesium sulfate with controlled hypotension can lower ecchymosis and edema of the upper and lower eyelids in rhinoplasty surgery by reducing bleeding.

Role of tranexamic acid in nasal surgery: A systemic review and meta-analysis of randomized control trial.

OBJECTIVE: Nasal surgeries (such as Functional Endoscopic Sinus Surgery, Rhinoplasty, and Septorhinoplasty) are popular procedures. But perioperative bleeding, eyelid edema, and periorbital ecchymosis remain problems. Tranexamic acid (TXA) is an antifibrinolytic, and it was used to reduce the perioperative bleeding. However, there is no enough evidence judging its safety and efficiency. Therefore, a meta-analysis is conducted by us to evaluate the role of TXA in patients undergoing nasal surgeries. METHOD: A search of the literature was performed until June 2018; the PubMed, Embase, Cochrane Central Register of Controlled Trials, and Google Scholar databases were searched for related articles using search strategy. Two authors independently assessed the methodological quality of the included studies and extracted data. Surgical information and postoperative outcomes were analyzed. Only randomized controlled trial (RCT) articles were included, and subgroup analysis was established to deal with heterogeneity. RevMan 5.3 software was selected to conduct the meta-analysis. RESULT: Eleven RCTs were included in our meta-analysis. There were significant differences in blood loss (P < .001), surgical field quality (P < .001), edema rating of upper (P < .001) and lower (P < .001) eyelid, ecchymosis rating of upper (P < .001) and lower eyelid (P < .001) when comparing the TXA group to the placebo group. However, the difference in operation time (P = .57) was not significant between the two groups. CONCLUSION: Perioperative TXA could reduce the blood loss and improve the quality of surgery field during nasal surgery, and it was helpful for reducing the edema and ecchymosis after nasal surgeries, but it has little influence in reducing the operation time.

Safety and efficacy of wiping lid margins with lid hygiene shampoo using the "eye brush", a novel lid hygiene item, in healthy subjects: a pilot study.

BACKGROUND: To evaluate the safety and efficacy of using a lid hygiene brush prototype to wipe the lid margins with lid hygiene shampoo in subjects with normal meibomian glands. METHODS: Twelve eyes of 6 subjects were all evaluated just before and after wiping lid margins using 1) tap water alone, 2) Eye Shampoo, 3) Eye Brush, or 4) both products, each during a different week. The results after using both products twice daily for 1 month were also evaluated. Wiping efficacy was determined by post-wiping scores for the remaining fluorescein-stained 0.3% Tarivid ointment fully applied to eyelids and lid margins under microscopic view illuminated by blue light just after performing each of the four lid hygiene methods described above. RESULTS: No significant deterioration in ocular conditions occurred. Eyestrain, eye discharge, and dryness decreased with tap water (P = 0.020), Eye Shampoo (P = 0.036), and Eye Brush (P = 0.014), respectively. Sensations of eye discharge increased after 1 month of using both products (P = 0.042). The wiping efficacy of Eye Brush, Eye Shampoo or both was significantly greater than that of tap water alone (two-sided test, P = 0.003, 0.003, 0.002), and using both significantly increased efficacy above Eye Shampoo use alone (one-sided test, P = 0.009). CONCLUSIONS: Wiping lid margins using Eye Brush enhanced the cleansing power of Eye Shampoo. A daily healthcare routine using both products could be a safe and effective option for daily lid hygiene. TRIAL REGISTRATION: UMIN000016905 . Registration date: March 24, 2015; the study was prospectively registered.

Effect of Eyelid Hygiene Detergent on Obstructive Meibomian Gland Dysfunction.

PURPOSE: To investigate the efficacy of eyelid margin cleansing with lid hygiene detergent in patients with obstructive meibomian gland dysfunction (MGD). METHODS: As a pilot study, we investigated the safety and efficacy of lid hygiene using tap water and/or lid hygiene shampoo in fourteen eyes of 7 normal subjects. All subjects were instructed to cleanse the eyelid margin with tap water and/or lid hygiene shampoo. As a main prospective clinical study, thirty-four eyes of 34 patients with obstructive MGD were enrolled. All subjects were instructed to cleanse the eyelid margin with lid hygiene shampoo at least once daily for 1 month. Ocular surface conditions were observed before and 1 month after study initiation. RESULTS: A significant exacerbating change (p < 0.05) was not detected after either method in the pilot study. In the main study, significant improvements were observed in tear break-up time (TBUT), lid margin lissamine green staining scores, vascular dilatation, and meibum status (p < 0.05). No significant improvements in corneal or conjunctival fluorescein staining scores, the mucocutaneous junction, lid margin deformation, or plugging were observed (p ≥ 0.05). Subjective improvements were observed in 27 subjects. Meibography revealed that 28 subjects had normal meibomian glands, and 6 subjects had meibomian gland atrophy. Significant improvements were observed in TBUT, vascular dilatation, and meibum status only in the group with normal meibomian glands (p < 0.05), but subjective symptoms and lid margin lissamine green staining scores improved in both groups (p < 0.05). No subjects experienced any problems throughout the study. CONCLUSION: Daily routine use of lid hygiene detergent can alleviate the symptoms of MGD regardless of meibomian gland atrophy.

Role of topical dehydroepiandrosterone in ameliorating isotretinoin-induced Meibomian gland dysfunction in adult male albino rat.

Isotretinoin broad effectiveness is limited by its detrimental effect on the Meibomian glands. Androgens have been reported to regulate the Meibomian gland function. Dehydroepiandrosterone (DHEA) is an androgen precursor considered as an efficient and physiological anti-ageing skin agent. This study aimed to investigate the role of the topical DHEA in ameliorating Meibomian gland dysfunction caused by isotretinoin employing different histological and immunohistochemical techniques. Twenty-four adult male albino rats were divided into four equal groups; control group, DHEA-treated group (1% twice daily for 3 months), isotretinoin-treated group (0.5mg/kg/day for 3 months), and both isotretinoin and DHEA-treated group. Meibomian gland specimens were processed for light microscopy. Immunohistochemical study was carried out using antibodies for proliferating cell nuclear antigen (PCNA), androgen receptor (AR) and estrogen receptor-alpha (ER-α). Sections from the isotretinoin-treated group revealed a reduction in the number and size of acini. Thickening and keratinization of the epithelial lining of the ducts were observed. Multiple degenerated acini and casts of acinar cells in the ducts of Meibomian glands were detected. Some dilated congested blood vessels and mononuclear cells were occasionally seen. A significant decrease in PAS reaction and a significant increase in collagen fiber content were detected. Immunohistochemical study revealed a significant increase in immunoexpression of PCNA in basal ductal cells coupled with decreased expression in basal acinar cells. Both AR and ER-α immunoexpression was significantly decreased. Minimal alterations were observed upon concomitant treatment with isotretinoin and DHEA as compared to the control group. Topical DHEA could prove to be beneficial in ameliorating isotretinoin-induced Meibomian gland dysfunction most probably through its androgenic effect.

Effects of orbicularis oculi flap anchorage to the periosteum of the upper orbital rim on the lower eyelid position after transcutaneous blepharoplasty: Statistical analysis of clinical outcomes.

BACKGROUND: The aging process affects the skin, muscle, and fat of the eyes in a different manner. Their individual rejuvenation would require specific surgical treatments according to their particular demands. In the present study, we analyzed the effect of an orbicularis oculi muscle flap fixed to the superior orbital rim to prevent lower eyelid dislocation during transcutaneous blepharoplasty. METHODS: The study was conducted retrospectively comparing pre- and postoperative images of two different groups of patients: group A (20 patients) treated with an orbicularis oculi flap and group B (17 patients) treated without the flap. Pre- and postoperative distances between the center of the pupil and upper border of the lower lid at the midpupillary line were measured in each photo and then compared and statistically analyzed. RESULTS: The mean age of the 37 patients was 57 years. From the estimated linear mixed model, we observed a significant effect of the presence of the flap (p-value < 0.0001). All the patients treated with the orbicularis oculi flap (group A) showed a cranial movement of the lower eyelid, although only minimally. All the patients treated without the muscle flap (Group B) showed a caudal movement of the lower eyelid. In total, 47% of the eyes in group B showed a positive variation of >10%. CONCLUSION: The study suggests that the anchorage of the orbicularis muscle flap to the upper orbital rim reinforces the lower eyelid's anterior lamellae. It efficiently stabilizes lower eyelid position after transcutaneous blepharoplasty, thus confirming clinical results and improving surgical outcomes even in patients with minimal or no eyelid laxity.

Lid Wiper Epitheliopathy in Soft Contact Lens Wearers.

PURPOSE: To evaluate lid wiper epitheliopathy (LWE) in soft contact lens (SCL) wearers on initial presentation and after using various SCL and solution combinations. METHODS: LWE was assessed in 253 habitual SCL wearers who attended a screening visit at one of three study sites. LWE was assessed using lissamine green and sodium fluorescein dyes (Korb scale); a final LWE grade was calculated as the averaged LWE grade of the two dyes. Eligible habitual wearers continued into the four study periods, during which they wore one of three SCL types (etafilcon A, galyfilcon A, or senofilcon A) while using each of four care solutions for 10 to 14 days in randomized order. Statistical analyses were performed using linear mixed models, testing for differences in LWE for subject characteristics and between three multipurpose (MPS) test solutions (BioTrue, OPTI-FREE PureMoist, RevitaLens OcuTec) compared to a hydrogen peroxide (Clear Care) control solution. RESULTS: LWE was present in 85% of habitual SCL wearers. LWE was not different for age (p = 0.28), sex (p = 0.99), race (p = 0.34), and comfort (p = 0.38) and not correlated with refractive error (r = 0.07). LWE was lower in habitual senofilcon A wearers (least-squares (LS) mean ± SE = 0.82 ± 0.19) compared to wearers of lotrafilcon B (1.34 ± 0.20; p < 0.02), comfilcon A (1.41 ± 0.21; p < 0.01), and other (1.18 ± 0.16; p < 0.03). Two hundred three participants completed all four study solutions with their assigned lens type; LWE was not different between the MPSs compared to the peroxide control solution across lens materials, except for less LWE for BioTrue (0.88 ± 0.17) versus Clear Care for participants wearing galyfilcon A (1.11 ± 0.18; p < 0.01). CONCLUSIONS: On initial presentation, LWE was present in 85% of habitual wearers and found to be independent of age, sex, race, comfort, and refractive error but dependent on habitual SCL type. There were no clinically meaningful differences in LWE between the MPSs and hydrogen peroxide solution for the three lens types studied.

Dual-Polymer Drops, Contact Lens Comfort, and Lid Wiper Epitheliopathy.

PURPOSE: This study compared a new contact lens rewetting drop containing both carboxymethylcellulose and hyaluronic acid (CMC-HA) with a standard drop containing carboxymethylcellulose only (CMC). Symptoms of discomfort typical in lens wear and lid wiper epitheliopathy (LWE) were assessed over a 3-month period in a diverse sample of contact lens wearers. METHODS: Adapted daily-wear contact lens subjects using hydrogel, silicone hydrogel, or rigid gas permeable lenses were enrolled in this prospective, randomized, double-masked, parallel-group, 90-day study conducted at 15 clinical sites. Subjects were randomized 2:1 to CMC-HA (n = 244) or CMC alone (n = 121) with dosage at least four times per day, along with their habitual lens care system. At baseline and at days 7, 30, 60, and 90, subject-completed questionnaires, bulbar conjunctival staining, LWE, contact lens distance visual acuity (CLDVA), and standard safety measures were assessed. RESULTS: At day 90, CMC-HA performed significantly better than CMC in ocular symptoms including dryness throughout the day (p = 0.006), and burning/stinging throughout the day (p = 0.02) and at the end of the day (p < 0.001). CMC-HA also performed numerically better for dryness at the end of day (p = 0.06). LWE staining was improved in the CMC-HA group at day 90 whereas it increased slightly in the CMC alone group, with a significant between-group difference (p = 0.009). CMC-HA also demonstrated greater reduction in conjunctival staining compared with CMC alone at day 90 (p = 0.08). No differences in CLDVA, contact lens wear time, acceptability, and product use were observed, and safety outcomes were similar between groups. CONCLUSIONS: The addition of HA to a standard CMC rewetting drop improves clinical performance. In this comparison of rewetting drop efficacy in contact lens wearers, LWE was a useful clinical sign for differentiating clinical performance.

Lid Papillae Improvement with Hydrogen Peroxide Lens Care Solution Use.

PURPOSE: To assess changes in lid papillae and symptoms after use of a hydrogen peroxide-containing solution (H2O2) for 3 months by symptomatic contact lens wearers. METHODS: This randomized, controlled, investigator-masked, parallel group study enrolled symptomatic lens wearers with at least mild lid papillae who habitually used a biguanide-preserved multipurpose solution (BMPS). Subjects were randomized to habitual BMPS or H2O2 for 3 months to care for their lenses. Lid papillae severity (0-4) was graded in four zones of each eye at baseline and at 30, 60, and 90 days. Subjects rated frequency and intensity of symptoms and completed the Contact Lens Dry Eye Questionnaire (CLDEQ-8) at the same time points. Lens cases used for 1 month were collected from subjects in the H2O2 group, and residual peroxide concentration was analyzed at disinfection time. RESULTS: In all, 131 subjects were randomized to H2O2 (n = 64) or BMPS (n = 67) and underwent post-baseline assessment. The H2O2 group showed significantly greater improvements in lid papillae from baseline to day 90 than the BMPS group (H2O2, least square mean [LSM] difference [baseline-day 90] in maximum score 0.904 [95% CI 0.744-1.064]; BMPS, LSM difference 0.423 [95% CI 0.271-0.576]; p < 0.001). Frequency and intensity of symptoms, including grittiness, end-of-day dryness, irritation, burning/stinging, itchiness, and blurry vision, were significantly lower for H2O2 than for BMPS at days 30, 60, and 90 (all p ≤ 0.045), as were mean CLDEQ-8 scores (3-mo scores 10.6 ± 6.30 vs.15.0 ± 7.29, p < 0.001). Residual peroxide concentration in 61 used lens cases ranged from 6 to 55 ppm (mean, 15 ± 8 ppm) and 95% of cases had residual peroxide less than 30 ppm. CONCLUSIONS: Symptomatic contact lens wearers using the H2O2 solution showed greater reductions in lid papillae and symptoms at 90 days than did subjects using BMPS. Cases used for 1 month neutralized peroxide at disinfection time to levels below those detectable by ocular tissues.

[Giant papillary conjunctivitis]. / Gigantopapilläre Konjunktivitis.

Giant papillary conjunctivitis is an inflammation of the conjunctiva, which is associated with immunological-allergic disorders, but is difficult to integrate as a defined type of illness. The deposits of contact lenses are responsible in predisposed wearers. They induce a special immune answer to their biochemical ingredients. In addition, roughness of the superficial corneal layers and the conjunctiva, even without any contact lenses after filtrating glaucoma surgery, leads to mechanically induced papillary formations. In former days these symptoms of building giant papillae were seen mostly in wearers of soft hydrogel contact lenses. Nowadays manufacturers have developed contact lens systems with a variety of material components, with an increase of protein and lipid deposits. In combination with the observed non-compliance of wearers regarding lens exchange and contact lens hygiene, GPC is an issue which should be taken into consideration again.

Effects of perioperative remifentanil with controlled hypotension on intraoperative bleeding and postoperative edema and ecchymosis in open rhinoplasty.

BACKGROUND: This randomized, double-blind study was designed to assess the effect of perioperative remifentanil with controlled hypotension on intraoperative bleeding, postoperative edema, and ecchymosis. METHODS: Fifty-two patients undergoing rhinoplasty were divided into 2 groups. The remifentanil group received 1 µg · kg(-1) intravenously as a bolus before induction of anesthesia, 0.5 to 1 µg · kg(-1) · h(-1) by continuous intravenous infusion during the operation. After anesthesia induction with propofol (2-3 mg · kg(-1)) and fentanyl (1-15 µg · kg(-1)), muscle relaxation was achieved with rocuronium (0.45-0.90 mg · kg(-1)). Mean arterial pressure was maintained at 50 to 60 mm Hg in controlled hypotensive anesthesia achieved using remifentanil infusion. Perioperative hemodynamics and bleeding; early postoperative pain and agitation scale; postoperative first, third, and seventh day edema; and ecchymosis were evaluated. Edema and ecchymosis were evaluated using graded scale from 0 to 4. RESULTS: Remifentanil reduced mean arterial pressure during the entire operative period and the first 30 minutes postoperatively (P < 0.05 for these comparisons). Intraoperative bleeding also decreased (P < 0.001). There was a significant decrease in edema in both upper and lower eyelid edema on the first and third days in the remifentanil group, although this difference was not detected on the seventh day (P(1upper) = 0.000, P(1lower) = 0.000, P(3upper) = 0.008, and P(3lower) = 0.002). Ecchymosis decreased significantly in both upper and lower eyelids on the first, third, and seventh days in the remifentanil group (P(1upper) = 0.000, P(3upper) = 0.000, P(3upper) = 0.002, P(3lower) = 0.002, P(7upper) = 0.049, and P(7lower) = 0.038). There were no differences in postoperative pain and agitation between 2 groups. CONCLUSIONS: Remifentanil with controlled hypotension may reduce edema and ecchymosis of the upper and lower eyelids, by reducing mean arterial pressure and amount of bleeding in rhinoplasty.

Long-term results of deeper muscle fibers recession of an inferior rectus operation.

PURPOSE: To report the efficacy in preventing lower eyelid retraction and long-term results of a new technique of inferior rectus (IR) recession for vertical strabismus and compare this method with the results obtained by a conventional IR recession operation. METHODS: This retrospective study included 35 patients who underwent a new IR recession method (study group) and 22 patients who underwent the conventional IR recession (control group) for vertical strabismus. In the study group, an IR recession was applied to the deeper fibers and included approximately 90% of the IR muscle thickness. This group was divided into two subgroups: small IR recessions (4 to 6 mm) and large IR recessions (7 to 8 mm). In the control group, an IR recession of the entire muscle was applied without exceeding 6 mm. The photographs were analyzed for lower eyelid position. Digital image analysis was used to standardize each patient's preoperative and postoperative photographs at final follow-up examination. The main outcome measures were the margin-to-reflex distance, lower eyelid retraction, and vertical deviation angles (at near and distance fixation). RESULTS: The mean change in margin-to-reflex distance after surgery was 0.03 mm in the small IR recessions group, 0.1 mm in the large IR recessions group, and 2.04 mm in the control group. Postoperatively, the lower eyelid retraction in the study group, which occurred after both small and large IR recessions, was significantly less than that in the control group (P < .001). There was no significant difference between the study and control groups in improvements in near and distance vertical deviations and success ratios (P > .05). CONCLUSIONS: At long-term follow-up, recession of the deeper fibers layer, including approximately 90% of the IR muscle thickness, was a procedure that minimized or eliminated the possibility of lower eyelid retraction and did not limit the success of strabismus surgery.
